This begins the reordering of the openstack-helm gates. This
deprecates the single node checks/gates that deployed the entire
stack in favor of single node checks/gates that are focused on
deploying charts with only their dependencies to reduce the
number of checks/gates required for a particular change. This also
moves the armada check to experimental, and moves the multinode
checks/gates to run as periodics. This will be followed up by
additional efforts to streamline these changes and incorporate
previous work targeting the same.
